Ys claims. v(ci. .2o-69) The invention relates to a weather strip, as

described in the present specification and illus-A trated in the accompanying drawing which forms a part of the same.

The invention consists essentially in encasing I-I A a compressible rubber tube in a rubber barrel having an extending liap'for nailing partially` covered by an overlap at the other side ofthe strip as pointed out in the claims for novelty following a description in detail of preferred forms of the invention.

The objectsof the inventionare to maintain railway passenger cars and other enclosures-free from drafts and dust, that are likely to permeate `through the closed sashes `in the frames and pervade the interior, and also avoid the percolai tion of water during great storms and to do this in a very simple manner by applying cushion seals permanently attached to storm windows and to sashes; to reduce the expense of attaching weather strips and the emcient and economical weather strip; -V

VLike numerals of reference indicate correspending parts in the various figures.

Referring to the drawing, the weather strip lil is preferably formed of pliable rubber sheet material or material having somewhat similar characteristics and is formed lof the outer packing vcase II which envelopes the inner flexible tube of securing the tubing to IS and which is secured to the reinforcing meme ber I8 and the packing strip I4. Y

yThe packing case II` contains a pliable soft rubber tube I6 ofcomparatively less pliability and greater thickness than the packing case I I.

The strip is nailed or otherwise secured to the sash or to the frame according to the particular application of theinventionand the cushion seal swaged inwardly securing the edge I2 of the cas` splayed ends of the cost of, the strip as well` ras furnishing a strip that may remain on for,` all time and not necessarily be removed at change of seasons; and generally to provide an" .and which is more adaptable to rougher surfaces pressed, against the adjacent surface usually the windowframe andA if the strip is all rubber it may be fastened in placewithout being cut until i `the installation for Ythat window is complete.

The packing strip portionIlI is retainedin position to theV metal reinforcing member I8 by turning the tail 24 upwardly and inwardly over the outer endof the strip portion I4, and by swaging the flange 2l ofthe body portion I5 of the rein-` forcing member I8 inwardly at the inner end of the packing strip III.`

'I'he casing i IV is secured to the metal reinforcingmember I3 in a similar manner, the tail piece I9Vbeing curled inwardly securing theedge I3 while the flange 23 of the body portion I5 is ing II to the reinforcing member I8.` p y The strap I8 is punched at intervals and the punchings 25 securely grip the rubber or other material and these punched holes also form the openings for entry of the fastening nails orscrews. Y

'I'he space between the packing strip It and the offset 20 of the reinforcing member I8 is fpacked* with soft yielding packing material 22, such as soft rubbenand is for the purpose of i filling in `the uneven surfaces of the woodwork or frame to which itis applied, `and which, upon pressure will compress where required ,thus forming a more regular closely fitting j oint.

In the reinforced form as'shown in `Figure 6 Y of the drawing,` the weather strip I (i ,must or should'be cut into the desired lengths before applying to the door or window and is somewhat moreeiicient,V although lacking the flexibility 3 of theformer form. Y

VThe principal throughout is entirely the same with the exception of the tailof the reinforcing member I8 which has the corrugated surface 23 and whereV a more rugged type of construction is required or preferred.

What I claim` is:-

l. A weather strip comprising an outer casing 45 l of pliable sheetmaterial encasing a iiexible inner tube of slightly greater thickness and compressibility than the said outer casing, said outer casing having extended edges forming flanges of unequal length adapted to be securely held inthe jaw portion of anirregular shaped metallic reinforcing member, saicl'reinforcing member having a tail piece projecting therefrom having secured-- thereto a flat flexible rubber packing strip, holes punched insaid tail piece at close intervals along its length, said holes adapted to receive the fastening means.

2. A Weather strip comprising an outer casing of pliable sheet material encasing a flexible inner tube of slightly greater thickness and compressibility than the said outer casing, said outer casing having extended edges forming anges of unequal length adapted to be securely held in the jaw portion of an irregular shaped metallic reinforcing member, said reinforcing member having a tail piece projecting therefrom having a pocket cavity at its base adapted to retain soft flexible packing, and said tail piece having secured thereto a flat flexible rubber packing strip,

Vholes punched in said tail pieceat close intervals along its length, said holes adapted to receive the fastening means, Y Y

3. A Weather strip comprising an outer casing of. pliable sheet material encasing a flexible inner tube of slightly greater thickness and compressibility than the said outer casing, said outer casing having extended edges forming anges of unequal length adapted to be securely held in the jaw portion of an irregular shaped metallic reinforcing member, said reinforcing member having a corrugated tail piece projecting therefrom having a pocket cavity at its base adapted to retain soft flexible packing, and said tail piece having secured thereto a flat ilexible rubber packing strip, holes punched at close intervals along its length said holes adapted to re` ceive the fastening means.
